The Don Johnson Look: white blazer, white trousers, loafers with no socks, and a colorfful shirt (light blue or pink), shades and at least a 1-day beard growth. This is for guys of course.

The Madonna Look: black mini skirt, leggings, black lace gloves with the fingers cut off, hair in the style she wore (all teased out with a side pony tail or you can look it up), lots of jewlery and makeup, black t shirt.

Really surprised that no one has mentioned the Valley Girl Look! You could also have a Valley Girl-speak contest!

Rubics cubes

an old Macintosh computer

an old Atari (with ebay, you might just get lucky!) Or you can just get one of those Atari classics games that you plug in to your tv.

a fun thing you could also do is rent a Karioke machine and get lots of 80's music and have a singing contest
